Recruitment agency Lime People Training Solutions, which rushed through Cameron's placement to get taxpayers cash from the Government's Skills Funding Agency, denied health and safety breaches.

But the company was found guilty following a trial and was today fined £75,000.

Akba and Zaffar Hussain arrive at court to be sentenced for corporate manslaughter

The firm earned a £4,500 fee out of Cameron's apprenticeship - with Hussain favouring youngsters for cheap labour and encouraging them to use 'inherently unsafe' work practices.

His son Akbar, 35, acted as supervisor and 'chief engineer' for the six-strong plant staff but after brief demonstrations to new starters he would allow other young apprentices to show them how to operate large machines and let them work unsupervised.

Akbar was given four months in prison, suspended for 12 months, 200 hours unpaid work and a fine of £3,000 heard after he admitted health and safety offences.

Huntley Mount didn't have any risk assessment forms, employees were unaware of any health and safety policies and dangerous machines had been tampered with to remove their safety locks so staff could work while parts were spinning.

During the hearing Cameron’s mother Joanne Hill broke down in tears as she said: "We believe Cameron’s deaths should have been and could have been prevented.

"When our first child got a job through a training agency doing something he enjoyed we were over the moon. He was 16 years old and doing something to be proud of. We were robbed of Cameron’s life and robbed of our son. And why? All for trying to do the right thing.

"Our child going to work on a pittance apprentice wage through a proper agency on a government approved apprenticeship. How could this happen? Where was the safety?

"Where was the training to help my boy? No day is ever going to be the same and it is all caused by people failing to pay that little bit of attention to make sure our boy was safe."

"That day I took Cameron to work, never in a million years did I think that when I went to collect him I would be greeted by two policemen and told my little boy had been in an accident.

"But was it an accident? The incident could have been and should have been prevented. This is a young boy working on a machine fit for no-one.

"All Cameron was trying to do was the right thing. My husband had to tell his brother and he said he would never forget his face when he told him his brother was dead. All of our children’s lives have been ruined through carelessness. I would say negligence. At least Mr Hussain still has his son.

"Cameron had many friends and was inspirational. His dad Anthony and I will be tormented for the rest of our lives that our son went before us. We have been failed for trying to be good parents."

The court heard how Huntley Mount had been 'blacklisted' by one recruitment company and regarded in the employment industry as a 'workplace to steer clear off' after apprentices sent to the factory had failed to achieve any formal qualifications.

The Hussains had also refused a number of offers of help to bring their factory up to correct health and safety standards.

Cameron, of Bury, started his apprenticeship on December 3, 2012, straight from high school and harboured ambitions of becoming an engineer.

He was sent by Lime People for an interview but it lasted a matter of minutes and was told to start the following week.

The tragedy occurred at 10.30am on January 8, 2013 when he was attempting to polish a piece of metal with the machine in operation in a process known as 'deburring'.

He was cut free by firefighters but was pronounced dead shortly afterwards.

Prosecuting, Bryan Cox QC said: "The company had, over a period of time, put profit before safety. Offers of risk assessment were rejected because of cost. Zaffer Hussain was aware of the importance of having them."

"Cameron was 16. He was a novice and ought to have been afforded careful training and supervision. The evidence indicates that after a brief demonstration he was put to work on a dangerous machine without meaningful supervision and full instruction about the dangers.

“There was little or no instruction given to staff about the risks associated with the use of equipment. The breaches were systematic and repeated. It was a long standing state of affairs.”

In mitigation defence counsel Dominic Kay said: “Cameron had only worked for the company for a short period of time but he was a young man who the company thought very highly of indeed.

"This is not a case of wilful breaches of health and safety – it is a case of failing to realise and fully recognise a risk. They didn’t think it was unusual to use apprentices.

'"As a small, modest local company they were paying wages commensurate with their size."

But Judge David Stockdale QC said: "This young man – inadequately trained, inexperienced, unqualified and virtually unsupervised – was effectively left to his own devices in the work shop operating fast running, unguarded machinery.

"To coin a well known phrase this horrific accident was an accident waiting to happen."
